To all whom t may concern.'

.Be it known that I, WILLIAM Rosie, a subject of thc King of GreatBritain and Ire land, of Albion Works, Gainsborough, in the county ofLincoln, England, have invented a new and useful Improved Clutch andBrake, of which the following is a specification.

The principal object of this invention is to provide a simple andefficient arrange ment of combined clutch and brake which can beactuated by the same initial operative means, movement in one directionputting the clutch into engagement while the brake is off, or at thesame time removing the brake should it not have been removed by the handlever provided for the purpose and movement in the other directionputting on the brake while the clutch is being disengaged, the apparatusto which the combination is applied being capable of being operated byhand, if required, when the operative means is in such a position thatthe clutch is disengaged and the brake is oil".

I will describe this invention with reference to the accompanyingdrawings, in which Figure 1 shows in side elevation and Fig. 2 in endelevation, with parts broken away, an arrangement of combined clutch andbrake constructed in accordance with this invention. Fig. 3 is atransverse section taken on the line A B of Fig. 1. Figs. 4 and 5 areviews (partly in section) at right angles to each other showing theclutch portion. Fig. 6 is a sectional elevation and Fig. 7 an endelevation, with part broken away, showing more clearly the clutchengaging means.

The pulley l, through which the apparatus is driven by a belt, or othergear, is loosely mounted on the main shaft 2. At the side of this pulley1 is a hand-wheel 3, or other wheel, (I will refer to it as a handwheel)secured to the main shaft 2. A transversely severed and consequentlyexpansible ring 4l is secured at one end to the pulley 1 and is situatedwithin a circular rim, wheel, or the equivalent, 5, secured to, or inconnection with, the shaft, 'which is shown as being a rim formed on thehandwheel 3, so that, when extended, the said ring 4 bears against theinternal periphery of the said rim 5. Through a bearing 6 in the pulley1 passes a short shaft, or stud, 7 parallel with the main shaft 2, thisshort shaft, or stud, 7 carrying, at one end, a cranked projection 8 forbearing on the free end of the expansiblc ring 4, to cause it to clutchthe rim on the hand-wheel 3, the other end of the said short shaft, orstud, 7 carrying a lever 9, carrying the antifriction roller 10 whichbears on a collar 11 capable of rotating with, and sliding upon, themain shaft 2, the said collar 11 having a grooved part 13, a plain part12 of larger diameter, and a coned part 14, between the parts 11 and 12,which coned part 14, when the colw larll is moved lengthwise (toward theleft hand in Fig. 4), will act on the end of the lever 9 and tilt it soas to turn the aforesaid short shaft, or stud, 7 and cranked part 8 andexpand the clutch ring 4 and so engage the driving pulley 1 andhand-wheel 3 and drive the main shaft 2. The said collar 11 is shiftedlengthwise by means of a fork 15 engaging with the grooved part 13 ofthe aforesaid collar 11 and carried by a bar 16 which is formed witheyes 17 to slide upon a fixed guide-rod 18, the said bar 16 alsocarrying a fork 19 for acting on a collar 21 with an inclined projection23 extending from the part 2l to the part 22, so that, when the bar 16is shifted lengthwise, in a direction which disengages the clutch (thatis toward the right hand in Fig. l), the antifriction roller 25 on thelever 24 is actuated by the inclined projection A23 and forced from thepart 21 of lesser diameter to the part 22, at a greater elevation, toapply a brake-strap 26 to a brake pulley 27, or the equivalent, on themain shaft 2.

When the main shaft 2 is to be driven by hand, t-he aforesaid collar 21can, by lifting the lever 2S (secured by its boss 2O to the said collar21) be moved through a partial rotation, so that the antifriction roller25 at the end of the lever 24, which applies the brake, takes up aposition on the said collar 21 at one side of the inclined projection 23and the brake is released, so that the main shaft 2 is free to be turnedby hand. When the bar 16 is moved to engage the clutch, and the inclinedprojection 23 on the collar 2l has passed beyond the lever 24 whichoperates the brake, the handle 28 will descend and the said collar 21will be turned so that the end of t-he said lever 24 will take up aposition on the part 21 of lesser diameter ready to be operated upon bythe inclined projection 23 on the said collar when the bar 16 is nextshifted into the position to apply the brake. The levers 9 and 24 whichbear (through the intervention of their antiriction rollers) on theaforesaid two collars 11 and 21 to engage the clutchl andapply the brakerespectively, may, for adjustment,

: oiil tog-compensate'for wear, be made in two falter-the position othev roller'constituting` parts hinged together (as shown at 29 and 30),the roller being carried by one part and the two 4parts being relativelyadjustable by means of inset-screw '(31 and 32) so' as to l thel end ofthe levers 9, ort-he lever 24.

` Any convenient means may be employed toislide the bar 16 onthe guiderod 18, for

example asl-shown in Figs. l and 2, it may" lconsist of ahand-lever 33Centered on a stud F 34C1o'n the-frame of thelmachine, the boss 35offthe said hand-lever 33 carrying an arm 36"provided with a pin 37engaging a slot 38 in a projection 39 from the said bar 16. lVha't Iclaim yis f 1i.V A; combined clutch and brake mecha- .1 -nism comprisingon a common shaft, a brakingfband and a clutch band, in combination withmeans for simultaneously engaging the y:clutch-"and freeing the brake,said means @comprising an 'actuating slide rod and operativeiconnectionsbetween the same and said brake land :clutch mechanisms, one ofV saidconnections comprising a cam member, to-
